Microinvasive Breast Cancer: ER, PR, and HER-2/neu Status and Clinical Outcomes after Breast-Conserving Therapy or Mastectomy

Abstract: MIBC has a favorable prognosis, and HER-2/neu overexpression, although highly prevalent, is not significantly associated with recurrence. Axillary metastases at diagnosis are small and infrequent. The cumulative incidence of LR after BCT is acceptable; however, our data confirm that negative margins (>2 mm) are required for optimal BCT outcomes.

“…In some cases, receptor status and Ki-67 stain were determined for the BC in situ component alone, due to MIBC focus/i dimensions. An almost complete concordance has been previously demonstrated between the microinvasive component and the in situ background [12,15]. Recorded histologic features of MIBC were type, grade, number/dimensions of foci, and distance from inked margins.…”

“…Particularly, axilla management and adjuvant therapies are frequent issues in the everyday clinical practice of MIBC. Some recent studies are present in literature dealing with the pathological and biological profiling of MIBC in order to find traits which might lead to higher risk cases and clinical implications [11][12][13][14]. So far there are many conflicting results in literature and it is difficult to distinguish higher risk groups for axillary involvement among MIBC patients.…”

“…Como ainda não há dados que permitam reconhecer quais pacientes estão mais propensas a apresentar acometimento nodal, parece razoável proceder à pesquisa de linfonodo sentinela no contexto do CMM, mas apenas naqueles em que um resultado positivo teria sua condução de tratamento pós-operatório alterada. Diversos estudos demonstraram que o esvaziamento axilar não se justifica no cenário do CMM [22][23][24][25][26][27][28] . O tratamento sistêmico do CMM é baseado nos parâme-tros usados para o tratamento da doença invasora que avalia estadiamento, dosagem de receptores hormonais e HER2.…”

“…O tratamento sistêmico do CMM é baseado nos parâme-tros usados para o tratamento da doença invasora que avalia estadiamento, dosagem de receptores hormonais e HER2. A recomendação é considerar terapia endócrina adjuvante com tamoxifeno ou um inibidor de aromatase, conforme avaliação individual, para pacientes com receptor hormonal positivo em CMM 27 . No entanto, a tomada de decisões sobre o tratamento com terapia endócrina adjuvante deve ser individualizada, avaliando os benefícios esperados com os riscos e efeitos colaterais.…”
